  • The robot can be controlled remotely through brain signals and can perform various tasks.
  • The team of researchers, headed by Professor Jose del R. Millain, particularly had disabled people in mind while working on the concept to restore a sense of independence to the disabled.
6) MDR-TB spreads less within households.
  • Unlike people with drug-susceptible TB, those with multi drug-resistant TB (MDR-TB) are less likely to transmit disease to others living in the same household (also known as household contacts), a study published in the journal PLOS Medicine found.
  • Although it may not be right to extrapolate the findings to the community level, within households, MDR-TB surely has ``relatively low fitness [be less capable of spreading] compared with drug-susceptible TB``.
7) Rosetta comet mission extended.
  • Europe announced its comet-chasing mission Rosetta would be extended until September 2016 and may end with the dying mothership touching down on the comet.
  • In a final flourish to the historic mission, the Rosetta spacecraft may be ‘landed’ on Comet 67P/ Churyumov-Gerasimenko.
  • Rosetta thus would rejoin its payload, the robot lab Philae, which it has nurtured throughout an odyssey spanning billions of kilometres.
8) Google adds `undo send` feature in Gmail.
  • Google is making it easier to steer clear of the trouble that can be caused by a misdirected or inappropriate email.
  • An option to cancel the delivery of an email within 30 seconds of hitting the send button is now a standard safeguard in Google’s Gmail as part of a settings change made this week.
  • The “undo send” feature had already been available for the past six years in Google’s experimental labs, but that required Gmail users taking extra steps to get it.

9) Kerala’s Trinity College of Engineering launches student satellite TASSAT project.

  • Trinity College of Engineering in Thiruvananthapuram, Kerala launched the Trinity Adrak Student Satellite (TASSAT) building project.
  • The student satellite project is scheduled for completion by 2018.
  • The satellite was named so because the funding for the ambitious initiative came from an Oman-based company called Al Adrak.
10) World`s first flexible and skin-like display developed.
  • A team of scientists led by Indian-American Debashis Chanda from University of Central Florida (UCF) developed a nature-inspired technique for creating the world`s first full-colour, flexible thin-film reflective display.
  • The findings were published in Nature Communications journal in June 2015.
  • This technology can help you switch your dress colour to a different colour in the blink of an eye, if someone at a wedding reception is wearing the same dress as yours.
11) MOM has enough fuel to last a few more years.
  • After outliving its six-month lifespan, the Mars Orbiter Mission (MOM) has crossed another hurdle - the solar conjunction.
  • ``It now has enough fuel to last a few more years``, said A.S. Kiran Kumar, Chairman of Indian Space Research Organisation (ISRO).
  • The sun had blocked Mars from the earth, snapping communication with the satellite, from June 8 to 22.
12) Google`s new self-driving cars cruising Silicon Valley roads.
  • Google’s self-driving bubble cars are chugging slowly and steadily down Mountain View streets, California.
  • The company revealed that the cars are now test-driving themselves around the city of Mountain View.
  • Their debut on public roads happened after more than a year of being tested on a former Central Valley military base and other private lots.
  • The tiny cars will join more than 20 of Google’s autonomous Lexus SUVs that have been steering themselves around Silicon Valley streets and freeways for years, and use the same software and detailed mapping system.

13) Light Combat Helicopter successfully clears hot weather trials at Jodhpur.

  • Indigenously developed Light Combat Helicopter (LCH) prototype has been successfully cleared hot weather trials at Jodhpur, Rajasthan.
  • The testing involved temperature survey of engine bay and hydraulic system apart from handling qualities, assessment of performance and loads at different all up weights etc.
  • With this successful test it will pave way for the Initial Operational Clearance (IOC), which is expected to receive it by the end 2015 and is likely to enter production from 2017-18. Earlier in March 2015, LCH had successfully cleared cold weather trials at Leh at a temperature of -180o C and at an altitude of 4.1 km.
